To all whom it may concern: described,pointed outin the appendedclaims,

of parts,such as will be hereinafter more fully In some stoves where a sheet-flue is used instead of the fines N and Q the extension 1' t' of the hearth-plate may be omitted and the edge of the hearth-plate constructed toabut the jamb A to close the chamber, leaving at all times the said chamber in condition to antomatically arrest the soot and cinders as they pass around thejunction of the fines. In other stoves, and which are the most prevailing pattern, either two or three vertical fines are used,forming ascending and descending fines, which if provided with my improved sootcollecting chamber may be made automatic by using the partition '7, forming an extension of the fine-strip S into the chamber,

the main object of which is to prevent any connection between the vertical fines through the said chamber, and the preferred form, construction, and arrangement are that the passages i i shall always be open, as plainly shown in Figs. 1 and 2, whether the rear vertical fine be of a sheet-fine or diving and ascending fine construction.

In regard to the application of this feature of my invention the said partition-plate may be permanently located in the chamber f, and thus divide it into individual chambers, one beneath each flue, and each chamber may be supplied with a suitable pan or drawer, if desired, or the said partition-plate may be located in the pan, as shown in Fig. 1, its upper edge registering with the strip S, or its cxtension'S cast on the bottom 13 at the division-line of said vertical fines. The front end of said pan g may have its end closed with a suitable casting, which may correspond with the skirting, so that when placed in position within the chamber f the said partition-plate 7 will register with the strip and the casting register with the skirting and close the inlet to the fine and chamber. Referring to Fig. 2, the said partition-plate is likewise placed in the pan in line to register, which registering is effected edgewise with the extension 8, and one side of the pan formed of or attached to a part of the removable skirting, which when in position closes the chamber.

Referring to Figs. 3 and 4:, which show the modified form, the extended hearth J forms a part of thechamberfand is closed by the hearth-plate 7t sliding over it, and if the said partition-plate be located permanently within the chamber, thus forming two or more chambers, which may or may not be provided with a pan, or the said partition-plate located in the pan in a position to register with the said vertical fine strip or strips and the said hearth-plate fitted to slide over its upper and outer edge of the same, so that when in closed position its inner edge 7; will register with the jamb A and effectually close the top of the chamber, but leave each division-chamber connected with the vertical and horizontal fines through the passages 2' 7?, by means of which dead-air chambers are formed beneath the vertical fines. An eddy or vortex formed therein by the passing currents of combustion deposits the soot and ashes automatically within the chambers.

In the fines O and P, I preferably arrange the fiat scrapers a a, which extend across the path of the horizontal fines. Centrally between their ends I pivotally connect the rod 1), which extends through the hole Z1 in the wall A. To their outer ends I attach asuitable operating-knob d, by which the scraper may be moved forward and backward through the fine-passage, conveying the soot before it to the passages 2' i It is desirable that these fine-scrapers be made automatic so far as their action on the bottom of the fine is 0011- cerned. To provide this means, I provide each scraper with the curved members?" 0", cast to the rear bottom edge, practically forming a segment of a wheel, thus adapting them to readily roll on the periphery of said members, the office of which is to lift the bottom edge of the scraper out of contact whenever pushed back by the rod 1). Centrally between the ends of the blades a suitable pivot connection is established which will permit the blade to turn upon the end of the rod in the line of travel. As shown, they are adapted to turn from an obtuse to a vertical position and are retained at right angles to the rod by the guides t, which extend from one side of the blade sufficient to support the slot t a short distance from the pivot, the rod closely fitting the slot, the length of which being sufiicient to permit the blade to turn, as desired, upon the members 0 r, the upper and lower ends of said slot acting as stop to retain it in its "aried positions as it is pushed or pulled through the passage. Thus it will be seen that thesaid scraper can only act to scrape the fine when drawn forward, and the act of pushing it back rolls the blade out of contact with the bottom of the fiue,the curved members supporting it in raised position.

Having thus described my inventiomwhat I claim is v 1. A scraper device consisting of a suitable plate or blades, means combined therewith for automatically moving their scraping edges out of active position when moved in one direction and means for operating and permitting said scraping edge to automatically assume an active position, when moved in an opposite direction over the surface to be scraped.

2. A fine-scraper, consisting of a suitable plate or blade, means combined therewith adapted to permit said blade to roll or rock in the line of travel, and having an operating-rod pivotally connected thereto, constructed and arranged at its pivotal connection so as to adapt it to permit said movement over the path on which it is arranged to travel.

3. A fine-scraper, consisting of a suitable plate or blade provided with rocking members extended from the bottom edge of one side of said plate or blade, adapted to support the said blade out of scraping contact,

and an operating rod pivotally connected thereto intermediately of its length, and furnished with means adapted to permit the blade to assume varied positions when operated, substantially as described.

4. A flue-scraper, consisting of a suitable plate or blade, provided with means adapted to permit the blade to roll or rock in the line of travel,an operating-rod pivotally connected thereto intermediately of its length, and furnished with means adapted to permit said blade to assume varied positions, and means for maintaining the blade at right angles to the rod, substantially as described.

5. In combination with a cooking-stove provided with a rear end vertical diving fiue and a connected horizontal flue and connected ascending flue, of a chamber permanently located beneath the former, and having a longitudinal slotted opening connecting them together, and furnished with a device for closing the chamber and providing access thereto, whereby a dead-air chamber is established, and an eddy formed by the passing currents as set forth.

6. In combination with a cooking-stove provided with rear end vertical diving flue, a connected horizontal flue, and rear side asoending flue, of a chamberpermanently located beneath the former provided with a longitudinal slotted opening connecting them together of a smaller diameter than the width of said chamber, adapted to overhang the upper edge thereof, and furnished with. a device for closing and providing access thereto, said chamber, whereby an eddy is formed by the passing currents and the sparks prevented from leaving the chamber as set forth.

7. In combination with a cooking apparatus provided with a rear end vertical diving flue, a connected horizontal fine and a connected ascending flue, a chamber permanently located beneath the former, a longitudinal slot-- ted opening connecting them together, of smaller diameter than the width of said chamber, adapted to overhang. the upper edge thereof, of a pan or drawer adapted thereto arranged in a position to receive the soot from the flues, and furnished with a device for closing and providing access thereto, combined to operate as set forth.

8. In combination with a'cooking apparatus provided with rear end vertical ascending and descending flues, and connected horizontal fines, a chamber permanently located beneath the vertical flues, and having a longitudinal slotted opening connecting each of them with the chamber, of a partition located in said chamber constructed and arranged and adapted to register with the dividing flue-strip of the vertical flues, whereby the same are extended to form a dead-air chamber for its individual flue, and means for closing and providing access thereto as set forth.
